1 Claims. (01. 248-352) This invention relates generally to jack structures and refers more particularly to a combination Jack and .brace structure for motor vehicles and the like.

One of the essential objects of the invention is to provide a jack with a brace that will effectively preventthe Jack from tilting or slipping out of place while applied to the bumper or other suitable part of a motor vehicle.

Another object is to provide a structure of the class described that may be readily collapsed when not in use so that it may be conveniently stored without-taking up too much space in the rear deck or luggage compartment of the vehicle.

Another object is to provide a structure that is simple in construction, inexpensive to manufacture, easy to. operate and effective for the purposes set forth. I

Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds,

standard H and has a pointed lower end I! engageable with any of a series of apertures or holes H3 in the supporting arm It. In the present especially when considered in connection with Figure 2 is a horizontal sectional view taken substantially on the line 2-2 of Figure 1;

Figure 3 is asectional view taken substantially on the line 3-3 of Figure 1;

Figure 4 is a fragmentary view of.the brace when jackknifed or partially folded;

Figure 5 is a fragmentary perspective view of the horizontal arm of the brace.

Referring now to the drawing, A is the jack and B is the brace of a combination structure embodying my invention.

As shown, the Jack A has a base plate III of circular configuration engageable with the ground, an upright or standard I I removably engaging the base plate lll at approximately the center thereof, a vertically movable lifting elementl2 on the standard, suitable mechanism l3 for raising and lowering the lifting element l2, and an operating lever is for said mechanism.

The brace B is substantially V-shape in elevation and has a diagonally disposed arm l5 and a horizontally disposed supporting arm l6. Preferably the diagonal arm I5 is pivotally connected at its upper end to the upper end of the instance, the diagonal arm l5 has two sections l9 and 20 pivotally connected at 2| and adapted to be held in extended position by a slidable sleeve 22. A collar 23 is fixed uponthe lower section 20 in spaced relation to the pivot 2| so as to limit downwardsliding movement of the sleeve 22. It will also be noted that the pivotally connected end portions 24 and 25 of the sections l9 and 20 containing the pivot 2| are recessed complementarily to receive each other so the over-all cross sectional dimension thereof will be substantially the same as the over-all cross sectional dimensions of-the sections l9 and 20. Thus, when the sections l9 and 20 are in extended position, as illustrated in Figure 1, the

sleeve 22 may slide freely over the end portions 24 and 25 from the upper section l9 to the collar 23 on the lower section 20 to hold the sections from jackknifing or swinging about the pivot 2|.

The horizontal arm l6 of the brace forms in reality a lateral extension of the base plate ID of the jack and is detachably connected thereto. Preferably such base plate I0 is provided at four diametrically opposed points thereof with slots or apertures 26, and the arm I6 has a substantially X-shaped downturned end portion 21 that is engageable with any of said slots 26, depending upon which one thereof is nearest the brace B after the base In and standard ll of the jack have been assembled. The apertured portion 28 of the arm I6 is corrugated, as illustrated in Figure 1, so that the holes l8- will be in the outermost inclined portions of such corrugations and thus be substantially in alignment with the diagonal arm l5. At the outer end 01 the horizontal arm I 6 is an auxiliary base plate 30 that is preferably pivotally connected to the underside of said arm for engagement with the ground and is substantially equal in width to the arm so it may assume a compact position in registration with the arm l6 when not in use.

Thus, from the foregoing, it will be apparent that the standard II and base plate IU of the jack may be assembled so that the stirrup portion 32 of the lifting element l2 of the Jack may be engaged in the usual manner with a bumper 33 or other suitable part of -a vehicle when it is desired to lift the latter from the ground. The X-shaped end portion 21 of the horizontal arm I6 maybe engaged with the nearest slot 28 in the base Ill of the jack, and the auxiliary base plate 30 may be turned at right angles to the arm l6,

as illustrated in Figure 2, to provide a good ground contact. The sections i9 and 20 oi the diagonal arm l5 may be arranged in extended position and held in such position by the sleeve 22. The pointed lower end II or the arm I! may be engaged with any of the apertures or holes i8 in the horizontal arm i8, depending upon the slope or condition of the ground under the brace, to insure the proper bracing efl'ect. This adjustment is particularly useful when the Jack structure is used on the side 01 a road where the ground is uneven, sloping or soft. Thus, the brace B will effectively hold the Jack A in proper position relative to the vehicle while the latter is being lifted or lowered and thereby will prevent damage to the vehicle due to any slippage or accidental movement of the jack relative to the vehicle with which it is engaged. When not in use, the standard II and base plate l otthe jack may be disassembled; the diagonal arm I may be disengaged from the horizontal arm I8 and jackkniied or folded after the sleeve 22 has been slipped upwardly on the section l9 clear of the overlapping end portions 24 and 25 or the pivotally connected sections; and the horizontal arm adiustably connected to the one having a downturned end portion engaging I may be disengaged from the base plate I0 01 the jack. 'Such collapsed structure can then be compactly stored without taking up much space in the rear deck or luggage compartment of the vehicle.

As an alternative, one section of the diagonal arm l5 may telescopically engage the other instead of being pivotally connected thereto as shown herein. Moreover. the connections between the diagonal arm l5 and standard II and between the horizontal arm Iii and base l0 may be different than those shown herein, as desired. Likewise, the auxiliary base so may be diflferent in configuration and be otherwise connected to the horizontal arm Hi, all as long as the brace structure B has the general configuration illustrated herein and is capable of functioning in a similar manner for the purposes set forth.

What I claim as my invention is:.

1. A combination Jack and brace structure comprising a jack having a ground engaging base and a standard on the base, and a brace for the jack having two arms, one being connected to the standard of the lack and inclining downwardly and outwardly therefrom, and the other forming a support for the first mentioned inclined arm and being connected to the base of the Jack.

2. A combination jack and brace structure comprising a jack having a ground engaging base and a standard on the base, said base being provided with an aperture, and a brace having two arms, one having a part engageable with the aperture in the base, and the other being connected the aperture in the base, and the other being connected to the standard and adjustably connected to'the first mentioned arm adjacent its outer end, and-an auxiliary ground engaging base carried by the first mentioned arm adjacent its outer end.

4. A combination lack and brace structure comprising a jack having a ground engaging base and a standard on the base, and a brace for the jack having a ground engaging member attached to and constituting a lateral extension of the base, and a diagonal member connected at one end to the standard and having its other end adjustably engaging said ground engaging member.

5. A combination lack and brace structure comprising a jack having a ground engaging base and a standard on the base, and a brace for the jack having a ground engaging member attached to and constituting a lateral extension oi the base, said member having a plurality o1 apertures therein, and a diagonal member pivotally connected at one end to the standard and having its other end alternately engageable with the apertures in said ground engaging member.

6. A combination jack and brace structure comprising a jack having a ground engaging base and a standard on the base, and a brace for the jack having a ground engaging member attached to and constituting a lateral extension of the base, and a sectional diagonal member connected at one end to the standard and having a tree end'adjustably engaging said ground engaging member, the sections of said diagonal member being movable relative to each other to shorten having a ground engaging member anchored inv one of the apertures in the base and projecting laterally from the latter, said ground engaging member having spaced apertures therein, and a diagonal member connected at one end to the standard and having its other end alternately engageable with the apertures in said ground engaging member.
